Solar Attic Fans are a essential part of keeping the climate in your attic controlled so that adverse conditions do not create problems for your home.

There are at least 3 reasons your home needs a solar attic fan.

The first is that excessive attic heat builds in the summer. Even if your roof has vents installed, they may not be enough to remove enough heat from the attic to prevent it from doing damage. Vents are passive – a solar attic fan actively draws heat out of your attic. Excess heat in the attic will radiate heat back into your living environment, forcing you to use more air conditioning, which will drive your energy costs up. In addition, too much heat in the attic will lead to cupping of your roofing shingles, and will shorten their lifespan dramatically.

Secondly, heat in the attic in the winter will cause snow on the roof to melt. As it runs down in freezing weather, it will reach the unheated overhang where it will refreeze, causing ice dams that can ruin shingles and force moisture under them, leading to rotting of the roof decking.

Finally, heat is not the only cause for concern. Moisture accumulates in the attic when steam is created in the home when cooking or running the shower. Moisture will eventually ruin your insulation and may lead to structural damage, mold, and mildew problems.

When considering energy savings alone, a solar attic fan will pay for itself. Saving your home’s structure and roofing is an added bonus. In addition, solar attic fans are easy to install if you enjoy DIY projects, and affordably installed by the professionals. A solar attic fan will last a lifetime, too, so you won’t need to replace it or your roof anytime soon!
